2.2 Pin description
The integrated gate driver provides additionally a
HIN(U, V, W) and LIN(U, V, W) (Low side and high
shoot through prevention capability which avoids
side control pins, Pin 7 - 12)
the simultaneous on-state of two gate drivers of the These pins are positive logic and they are same leg (i.e. HO1 and LO1, HO2 and LO2, HO3 and responsible for the control of the integrated LO3). When two inputs of a same leg are activated, MOSFETs. The schmitt-trigger input thresholds of only former activated one is activated so that the leg them are such to guarantee LSTTL and CMOS is kept steadily in a safe state. compatibility down to 3.3 V controller outputs. Pull- A minimum deadtime insertion of typically 300 ns is down resistor of about 5 k is internally provided to also provided by driver IC, in order to reduce cross- pre-bias inputs during supply start-up. Input conduction of the external power switches. schmitt-trigger and noise filter provide beneficial noise rejection to short input pulses.

The noise filter suppresses control pulses which are The RFE pin conbines three functions in one pin: below the filter time tFIL,IN. The filter acts according to programmable fault clear time by RC-network, fault- Figure 4. out and enable input. The programmable fault-clear time can be adjusted IM828 by RC network, which is external pull-up resistor and Schmitt-Trigger capacitor. For example, typical value is about 1ms at HINx INPUT NOISE LINx 1 Mand 2 nF.
